A device for sampling bulk material comprises a tube 5 having closure means 15 mounted on the end of the tube which is arranged to be thrust into the material, the tube being arranged to be releasably connected to an ejector 6 by means of an expandable catch 7, 8, 9 so that the tube and ejector may be either moved independently or together by means of a piston-and-cylinder device 1, 2, 3. The catch device comprises plungers 8, 9 are loaded outwardly by a spring 7 and provided with rollers 10 adapted to run on the wall of the tube. The plungers are normally engaged in bores 11, 12 in the tube so that when the piston 2 is actuated and the closure means opened the tube is thrust into the bulk material. The closure means are then closed and the tube raised until the plungers are aligned with plungers 13, 14 which, upon actuation of piston devices, move into the bores 11, 12 thereby forcing the plungers 8 out of engagement with the bores; the ejector can then be moved downwardly to eject the sample after the closure means have been opened.

[Also in Division G2] Sheet separators.-In apparatus for feeding sheets from the top of a stack into a sheet feeding system, means to ensure that two sheets are not fed together comprises a restricted passageway defined by an upper guide 106 having a lower surface generally parallel. to the direction of sheet movement from the stack 103, and a lower guide 104 extending upwardly from the bottom of the stack toward, but spaced from the guide 106 to block the passage of two sheets. The guide 106, Fig. 3 (not shown), comprises two parallel offset parts 108, 110 joined by a bent part 112, and the lip 105 of the lower guide 104 is located below the guide 106 at a level which causes the separated sheets to bend upwardly. The sheets are separated by two rollers 80, 82, Fig. 4 (not shown), secured to a shaft 84 mounted in arms pivoted about a shaft 86, and driven intermittently from the shaft 86 by belts 88 and pulleys. The drive to the shaft 86 is through an electromagnetic clutch 128 from an endless chain 132 driven by a motor 138. Sheet feeders.-As described, the invention is applied to a photocopying apparatus of the electrostatic type, wherein copy sheets are stacked at 103 in a compartment 24 closed by a hinged cover 76 which raises the separator rollers 80, 82 when it is opened. Each separated copy sheet is forwarded by a pair of driven rollers 118, 120, Fig. 4 (not shown), into a shoot 141, 142, over a guide roller 140, between driven rollers 143, 144, through a corona charging unit 27, between driven rollers 152, 154, and over an endless drive belt 160 where it receives an image of an original document from an optical system. The copy sheet is then passed through a developer tank 44 and discharged by feed rollers and a conveyer belt 198 on to a plate 52. All the rollers and belts are driven by the endless chain 132 which drives the separator rollers. The document to be copied is inserted through a slot 30 in the casing, and is fed by rollers also driven by the endless chain 132. Both the document and the copy sheet act on switches which control the clutch 128, so that they arrive simultaneously at the copying positions.
